Hi peggy, this is an xfrog tree (from scratch, though). It is a really nice program, though it requires a different approach to building stuff than other 3d programs (basically you are manipulating mathmatical functions). For those interested in giving this little guy a test run, I'll post a link to this thread tonight. I thought I uploaded the most recent version, but it apparently created a single file of 0 length (it was a real fast download, though:) I don't have access to it here, so it will be after 6:00 before I can get 'im uploaded. eric
